Cocoa: drag any type of file

I am trying to create a drag and drop scope that accepts any type of file and will upload it to the server (using ASIHTTPRequest). I reviewed the following example that Apple provides:

http://developer.apple.com/library/mac/#samplecode/CocoaDragAndDrop/Introduction/Intro.html

but it only covers dragging and dropping images. How can I configure my drag and drop operations to work with any type of file?

Thanks.

Judging by the message, you probably just need to register your register for NSFilenamesPboardType instead of imagePastBoardTypes to get arbitrary file types.

Kind of related, but adding this in case it is useful to someone:

If you just want to process any file dragged onto the application icon (it’s not necessary to be a document-based application):

In .h:

 - (void)application:(NSApplication *)sender openFiles:(NSArray *) fileNames;

In .m:

 - (void)application:(NSApplication *)sender openFiles:(NSArray *) fileNames { NSLog(@"Files dragged on: %@", fileNames); }

In your xxx.plist, create a new entry in CFBundleDocumentTypes:

 <key>CFBundleDocumentTypes</key> <array> <dict> <key>CFBundleTypeExtensions</key> <array> <string>*</string> </array> <key>CFBundleTypeName</key> <string>NSFilenamesPboardType</string> <key>CFBundleTypeRole</key> <string>None</string> </dict> </array>
